Arrowmax 64P 51T 7075 Hard Pinion Gear - AM-364051

The Arrowmax AM-364051 is a 64 pitch, 51 tooth pinion gear machined from 7075 aluminium for use in RC car drivetrains. Designed for competitive and performance-oriented builds, this pinion gear is a precision-cut component intended for 1/10 and 1/12 scale RC cars running 64P gear systems. The 7075 aluminium alloy construction offers a harder, more durable finish than standard 6061 alloy, making it well suited to high-RPM motor setups where gear wear is a concern.

Key Features

• Machined from 7075 hard aluminium alloy for increased hardness and wear resistance compared to standard aluminium pinions
• 64 pitch (64P) tooth profile — must be paired with a matching 64P spur gear
• 51 tooth count suits lower gear ratios, typically used to reduce top-end speed and increase torque at the wheels
• Precision CNC machining ensures consistent tooth geometry for smooth, low-noise mesh with the spur gear
• Lightweight aluminium construction keeps rotating mass low, which benefits motor response and efficiency

Compatible With

• RC cars and buggies using 64 pitch (64P) drivetrain gear systems
• Commonly used in 1/10 scale touring cars, pan cars, and 1/12 scale on-road RC vehicles
• Compatible with standard 3.175mm (1/8 inch) motor shafts — verify shaft diameter before ordering
